One 1 obj ect of this inventionisgjtc provide a from thejcomb. degrees ,fso that the cutlting action of the combl may be accuratelyand Another object is to provide a hair-c tting comb having a screw-operated adjustment de, vice connected to the blade. for moving the blade the comb with whichit is associated.

Another object is comb of the foregoing character having a screwoperated'Y adjustment device which is quickly and easily detachable fromthe blade holder so that the blade may be changed rapidly with a simple operation.v

I-Iitherto, in .hair-cutting. combs it has been difficult toV control the cutting action'oi the cutv'ting blade by reason of thegfactrthat the blade was clamped roughly in positionby a clamping nut or was'moved roughly by a coarse rack and pinion." In the one case, when the clamping nut becamesl'oosened, the blade shifted its position andconsequently altered itscutting action'. In

the other case,v avfslight pressure on the cutting blade or its` holder pushed these in one direction or-the other so as toalter the adjusted position of the blade vand 'consequently to alter its cutting action. The present invention eliminates these diiculties vby providing a precise y' invention relatesitoihair-cuttingldevices, I

The earV 3I also passes through a rectangular hole 34-in a'cutting Y blade, generally designated 35 v(Figure '7)-fa'n'd l v likewise through a rectangular ho1e`36in a bladeholder, generally designated 31.1 The bladey 35 also has a pair of spaced rectangular holesA v3i) on opposite sides of the hole 34, the latter being considerablywider than the thickness of the ear 3|, so as to permit the latter to slide'sidevvi'sel The hole 36 in the blade holdervS'I is likewise wider than the thickness of the ear 3 I for the same purpose, as clearly shown in'Figure 2. The blade 35 Ais provided with cutting edges 39 alongfits opposite edges. The bladeholder 3l' is provided with rspaced rectangular lugs 40 projecting downward from the'underside of its platelike body fIfI (Figure 9) these being spaced so 'as to extend through the blade holes 38 into thegrooves I 6 .(Figure'2).

- The body 4I and blade '35 are in the form of recthe holes 38. The assembly of the Ablade '35andj blade-holder 31 is then pushed rearwardly along the recess I5 until the aligned-.holes 34,-36 comeu into alignment with hole I9 in the position shown in Figure 6. The user then inserts the ear 3l Lof the clip 32 upward from below through the left- ?.Shan'd fsidesa of4 the holes Il 9,534,535. until fthe top of i' thefear |..1w-ith2its.hole"30 .emerges abovethe top 'of-thebladeholder'l, as shownin Figure 3. ;The clip 32 is then moved tothefright fromlithe positi'onlfshownin'Figure 6, to that shown vin".Figure l, 1^
